most hermits drop their shell when they outgrow it and hunt down a bigger shell. If they cannot find one, they will seek out a snail with a shell that is bigger, kill it, and then steal the shell.

Emerald crabs, strawberry crabs, Acro crabs, etc molt

Yup. That's what happened to me. I had some empty shells all over the tank but i guess the hermit wanted the snail's. So in the morning i noticed a Hermit with a snail shell...but now he has to dodge my yellow tang trying to pick at the algae on the shell...ha ha ha
